- Product: GY-471 MAX471 Current Sensor Module
- Operating voltage: 3V – 36V
- Operating current: +/- 3A
- Sensor: MAX471
- Soldering: Unsoldered components
The MAX471/MAX472 are complete, bidirectional, highside current-sense amplifiers for portable PCs, telephones, and other systems where battery/DC power-line monitoring is critical. High-side power-line monitoring is especially useful in battery-powered systems since it does not interfere with the ground paths of the battery chargers or monitors often found in “smart” batteries.
The MAX471 has an internal 35mΩ current-sense resistor and measures battery currents up to ±3A. For applications requiring higher current or increased flexibility, the MAX472 functions with external sense and gain-setting resistors. Both devices have a current output that can be converted to a ground-referred voltage with a single resistor, allowing a wide range of battery voltages and currents.
An open-collector SIGN output indicates current-flow direction, so the user can monitor whether a battery is being charged or discharged. Both devices operate from 3V to 36V, draw less than 100µA over temperature, and include an 18µA max shutdown mode.
